noon-OPERATNG MEANS.

Application ledllarch 31, 1926. Serial No. 98.812.

My invention relates to door-'opening and closing means permitting of aperson'effecting an opening or closing of the doors at a point somewhatremote therefrom.

The invention more particularly relates to the type of door-operatingmeans shown in United States Patent No. 1,508,270, granted to lneSeptember 9, 1924, in which a switch is mounted on a post or the likedistant from a garage or other structure, the doors of which are to beopened and which includes an electric motor having operative connec tionwith the doors as well as manually operable switches in circuit with themotor to throw the motor into and out of action and to place the doorsunderl the control of the operator.'

The general object of my present invention. is to provide adoor-operating means of the general type referred to improved in variousparticulars especially with regard to the means to operate a travellerfrom the motor as well as with respect to the circuit and the devicesembodied therein.

The nature of my invention, its' distinguishing features and advantages,will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part ofthis speciiication, it being understood that the drawings are merelyillustrative of one example of the invention. I v

In the illustrated example of my invention the numeral indicates astructure which may be a garage or the like. The structure 15 is shownwith swinging doors 16 to open and close by mechanism compri-sed in myimproved devices. To each door is pivotally secured a rod 17, said rodsbeing convergent and connected at their inner ends with an element 18advantageously in the form of an angle bracket, said element 18 having astem 19 bolted thereto, said stem having a plunger 20 operating in acylinder 21. Springs 22 in cylinder 21 bear against opposite Vfaces of aplunger 20. The cylinder 21 with the springs 22 and plunger 20 with stem19 form an indirect -connection between the head 18 and atraveller 23.Said traveller is driven by an endless chain 24, the`illustrated.connection being by a stud 25 on chain 24 and entering a vertical slot26 in traveller 23, said stud having a. roller 25.

The chain 24 runs over an idler sprocket wheel and a driven sprocketwheel 28 driven in any suitable manner from the shaft on an electricmotor 29, there being a reducing gear 30l conventionally indicated inthe pres: ent example as the drive connection between the shaft 29 anddriven sprocket 28. Said reducing gear is of ywell known form and doesnot constitute part of the present invention and therefore needsnofurther velucidation. The traveller 23 has a tubular guide bar 32 in aframe 33 which also mounts the motor 29. In practice, rods 17 haveincorporated therein` turnbuckles 117 for adjustment.

Frame 33 has a longitudinal switch shifting bar 34 mounted in the endsof the frame to have limited sliding movement thereby when said rod istripped by traveller23 as y switches 48.l

the opposite end. A switch base 36 is disposed adjacent the rod 34between two tingers 37 on'said bar 34. To swltch base 36 are pivotallysecured two switch blades 38, 39, said blades having fixed pivots 40,about which the blades may rock. The swltch blade 39'is adapted to havecontact with switchleaves 41, 42 and the switch blade 38 is adapted tohave contact with two switch leaves 43, 44 according to the direction 1nwhich the base 36 is moved by the fingers 37 on shift rod 34.

Relays 45,-46 are provided in clrcuit wlth motor 29'; in said circuitalso are pairs ot manually operable and normally closed switches 47 aswell as manually movable In the motor circuit alsoand remote from thedoors 16, to be controlled by one approaching or leaving a garage, forexample, is a switch designated generally by the numeral 49 which 'iskey-controlled,-

being provided with switch lock 50, the numeral 51 indicating a lock forthe casing of switch 49. The switch 49 includes a lswitch assemblage 62having spaced terminal emergency stop for the doors and includesv spacedterminals 56 and a slide 57 having a bridge piece 58. Slide 57 issubject to a spring 59 and slide 54 is subject toa spring 60. The spring60 normally tends to maintain the switch open by maintaining the bridgepiece 53 out of engagement with the terminals 52. Springl 59 normallymaintains switchI assemblage 63 closed. The switch 49 is here shown asmounted on a post 61.V

The switehes47 and 48 may be anywhere conveniently located about thestructure 15.

With the above described'assemblage, the traveller 23 serves to actuatethe door-operatingy rods 17. With the initial movement of said traveller23 in either direction the force exerted by the'traveller is absorbed bythe springs 22' and upon compression of a spring, the movement of thecylinder 21 with the `traveller will act on the plunger rod 19 andthrough the element 18 or equivalent connection, the rods 17 will bemoved to swing the doors 16. As traveller 23 approaches a sprocket wheel27 Vor 28, a finger 123 on said traveller engages a trip 35 ork 135 toshift rod 34 for making or breaking the circuit through the fingers 37trated circuit for carrying out the example of the invention shown. Inthe normal position of the parts when not in operation, the circuit isopen at the armatures 145, 146 because the relays 45 and 46 arede-energized- When the motor is not running and the dcscribed automaticswitch controlled by the shifting fingers 37 is conditioned for anoperation, either for opening the doors 16 or closing the same, after aprevious operation, then, the switch blade 39 may be engaged with switchleaves 41 and 42 and therefore in electrical connection with saidleaves, or, switch blade 38 may be engaged with the switch leaves 43, 44and therefore in electrical connectionv with said leaves 43, 44. Theswitch blades 38, 39 are insulated from each other by the base 36 andoperate without contacting with each other. The switch operating fingers37 move the switch blades simultaneously so that the blade 39 willcontact with leaves 41, 42 or the blade 38 will To open the doors eitherof the switches `by wire f to and through switch leaves 41,

through blade 39 to wire g and to the winding of relay magnet 45energizing said magnet and attracting the armature 145, bringing saidarmature into contact with the terminal h associated with the wire d.Hence, the circuit will be closed between the armature 145 and saidterminal h so that the current iows from wires a and b to the wire dwhich connects by wire Z with switch leaves 43. It will be observed thatat this time a circuit is established running from leaves 4 1 and blade39 to and through switch leaves 42 and by wire to switch leaves 44 andby wire j to motor 29 and to the negative lead 7c of the supply circuit.Themotor 29 now receives its current for continuous operation of themotor for the opening of the doors.

It is to be noted here that when the ingers or hand which temporarilymaintained a Switch 48 0,1' the switch 62 closed, is removed from saidswitch, that is temporarily closed, the circuit is broken through saidtemporarily closed switchbut the motor is in circuit with the supplyleads through the -energizing of relay 45 and thus the current flowsthrough armature 145 fand terminal h and -wire d to the motor.connectionsdescribed. As4 the motor operates, it drives thesprockctwheel 28 and through chain 24 causes the traveller 23 to movetoward the trip on rod 34. Upon the engagement of the finger 123 ottraveller 23 with the trip. 35, rod 34 is moved longitudinally, thuscausing the lingers 37 to throw the lswitch blade 39 out of engagementwith the 145 to drop out of engagement with terminal h, whereby allopation of the apparatus is stopped. and the doors will have arrived atthe open position.

The automatic switch involving the blades 38, 39 when the motor 29 andrelay 45 are thrown out of operation as described, conditions theapparatus for the closing opera'- tion of the doors. blade 38, it is to.be noted, isengaged with the leaves 43, 44 and the switch blade 39 is'out of engagement with the switch leaves 41, 42. l

In order to effect the closing of the doors 16, one of the switches l48is thrownto the closed position or the switch62 lis closed byswitchassemblage G2 by turning the key in the direction of the arrow'marked operate in Figure 7. The temporary/closing of the circuit throughthe normally closed switches.

At the same time current flows from leaves 43 and throughswitch blade 38 to switch leaves 44 and to wire j and through the motor29 to negative lead k. As the motor is thus energized for the closin ofthe doors, thesprocket 28-is again driven, and therefore, sprocket chain24, until the linger 123 of traveller 23 engages the trip 135 and againthrough iingers 37 shiftsl switch base 36, thereby throwingthe switchblade 38 out of engagement with the switch leaves `43, 44 and throwingthe switch blade 39 into engagement with the switch leaves 41, 42. Asthe current is broken at the switch leaves 43, 44', the relay magnet 46and the motor 29 will be cut out and the doors will have reached theirclosed position.

If it should be desired to arrest either the At this time the 4switchthe insertion of al key into the lock 50" of switch 49 to close thecircuit through.

I would state furthermore that while the illustrated example constitutesa'practical embodiment of my invention, I do not limit myself lstrictlyto the exact details herein illustrated, since, manifestly, the same canbe considerably varied without departure from the spirit of theinvention as defined in the appended claims.
